If you LOVE music these are the speakers for you. The lushness & depth of field are just incredible. When auditioning speakers I had settled on either the Logan Sequels or Definitive Tech. BP-3000. I stumbled upon a great deal on some floor model Quests that I couldn't pass. The determining factor between the two speakers was my taste of listening. As I stated before, I LOVE music. Have ever since I was a kid. If the persons that gave the low rating are more interested in movies I can see why they gave the rating they did. I don't feel the Quests alone can deliver the punch needed for movie watching. Even though they are rated below 30hz, the just don't have the punch when watching a scene such as the train derailment from The Fugitive. It does sound good, but needs a sub to give them that extra punch. Power is also a concern. They need lots. I have an Aragon 8000ST driving these bad boys and they eat it up. Long story short, if you like listening to tunes they can't be beat (except maybe by the Logan Statements). If you want them for movies, get a good sub to go along with them.

I reviewed this previously. Some are critical of the bass produced here. If that's true..CHANGE YOUR CABLES. They make a big difference in the bass. Tekline solid silver work beautifully for me. You also cannot cheat on other components. These spekers will ruthlessly show up inferior components.

Also, try adjusting placement. Since they radiate bi-directionally, it will affect bass as well as other frequencies.

This is one of the finest speakers in the world. Anyone who would rate them one or two stars is not an audiophile, and must not understand what they are doing.

best speaker so far cleanest purest sound ceep them to death you need a bigg room placement is evrything if the build in woofer is boomy placement is wrong or mayby jour room is too small or mayby the room creaates standing vaves i love these martin logans lissning too guitarr strings who needs moore detail martin logan quest forever

The Quest Z tuned out to be a disappointment, even after weeks of experiementation on placement.

The electrostatic element produces a very nice upper end.

The bass response is largely non-existent unless the pre-amp's tone controls are used. But using the tone control to boost the bass produces a muddy effect. The lack of clarity in the lower end is a killer for me.
